SPECIFICATION forming part of Letters Patent No. 731,610, dated June 23, 1903.

Application filed October 13 19(12. Serial No. 127,1l5. (No model.) I

T0 611 whom, it may concern:

Beit known that I, WILLIAM HUBEET PAYNE, a citizen of the United States, residing at Monrovia, in the county of Los Angeles and State of California, have invented new and useful Improvements in Fumigating-..

'1ents,of which the following is a specification.

My invention relates to tentsfor fruit-bearing and other trees incident to fu:

migation thereof; audit has for its object to.

provide a graduated tent calculated when it is placed over a tree to apprise an operator With the foregoing in mind the invention will be fully understood from the following description and claims when taken in connection with the accompanying drawings, in which- Figure 1 is a view illustrating a graduated tent constituting one embodiment of my invention as it appears when placed over a tree, the tent being partly broken away. Fig. 2 is a ,plan view of the tent as it appears when spread out.

Similar letters of reference designate corresponding parts in both views of the drawings, referring to which A is my improved tent, which is preferably formedin one piece of textile or other suitable material, andBB are the graduations of the tent-i. e., marks or lines formed in oron the material at a suitable distance apart,

The grad nations in the preferred embodiment of the invention are concentric circular lines,- as best shown in Fig. 2, and when the tent is of a size to cover trees up to thirty-six feet in height experience has shown that the graduabe difierentiy colored, as shown in Fig. 2, or may be otherwise difierentiated. It is not essential, however, to differentiate the graduations, since the operator is enabled by counting the number of graduations or rings resting on the ground after the tent is placed over a tree to determine the quantity'of fumigating material to beused; In using the improved tents an operator cognizant of the quantity of cyanid of potascovering 'sium or other fumigatingniaterial which it is proper to use when any one of the graduations Brestsabove and next to the ground accompanies the tent through an orchard. When the tent is placed over the tree, the operator ascertains the number of the graduationsresting on the ground or the particular graduation resting above and next to the ground and measures the proper quantity of fumigating material or chemicals and places it under the tent. After the tree covered by the tent is thoroughly fumigated the tent is removed and placed over another tree, and the operation described is repeated.

It will be readily appreciated from the fore going that myimproved tent apprises the intelligent operator of thequantity of fumigating material to be used for each tree, and thereby assures the uniform fumigation of all of the trees of an orchard and avoids Waste of fumigating material and makes fumigatioua certainty and not guesswork, as at present. 1

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. As an improved article of manufacture,

a graduated tent for use incident to the fumigation of trees. I

2. As an improved article of manufacture, a tent adapted to be placed over trees, and having marks or lines arranged at intervals between-its bottom and top.

3. As an improved article of manufacture,

a tent adapted to be placed over trees, and

having difierentiated marks or lines arranged at intervals between its-bottom and top.

L-As an improved article of manufacture, atent adapted to be placed over trees, and having a plurality of equidistant, concentric I circular lines for the purpose described. tions may be placed as much as two feet apart. When desirable, the graduations may.

tiated from each other.

In testimony whereof I have hereunto set my hand in presence of two subscribing witmesses.
